EGG-TRAY.

T o alllfwlzom t may concern Be it known that I, HJALMAR A. SwartsoN, a citizenrof the United States, residing at Clay- Center, vi'n the county 0f Clay and' State of Nebraska, have invented a new and usefu1`Egg-Tray, of which the following is a specification.

This invention relates' to egg trays for.

use Ain connection with ineubatoi's, and among its several objects contemplates a device of this character adapted to hold a plurality `oit' eggs and havinghmeans for rolling the eggs whenever desired or essential. v 'f Another 'object of 'the present invention is .to provide va device of this character embodying a pair fofrollers and a belt or endless 'apron trained over the rollers, and having means for adjusting one of the rollers to 'tighten and loosen the belt, .and the other rollers being adapted lto'he rotated in order .v to shift thebelt or'a'pron which foi'ins a support for the eggs. f

` This yinvention alsoaims'to'produce such -a device which shallbe comparatively sim' ple and inexpensive 1n its eonstru'ctionas "well as convenient and efficient in use.

A furthervobject ofthe .present invention cated embodyinv an egg support adapted'to be shiftediandj'embodyin'gan egg-holder having' elongated egg-receiving openings of practically the same dimensions-as the eggs order to prevent the' egg'svfrom rotating -about 'vertical aXesand which eggholder is seatable over the: egg support so that' theleggs' are liiited ,slightly ont of the I.openingsand may tiel rolled ,by .shifting the eggtsupport laterallyfof.thf'openingsf- 40 vention' isfto provide fa device Voftli: char,-

Referring speciieallyvto thedrawings, the

main frame, which is rectangular4 in confl tour, has been designated by thenumeral 7, and this frame -is ,provided with an upper edge of the frame. Thisframe has the inner recesses 22 and 2'2"' in one 'side thereof, the respective -pairsf of recesses 22-22Il and 22h-Qc being arranged anche `Ways or -channels 2,1' and 211. extend -u' wardly from thevrecesse's 22jand 22h to't ej. seat 9, andthe frame l7 is pro-videdwitha y .upper rabbet 8 formingaseat 9 within the' the" two sides. 1 l

bore or opening -18 extending outvv'ardlyj fromthe recess 22','the outer end :ofthe 1 bore 18 being. coi'inter-bored in orderT to vpro-I 'vide, afsocket or recess 17in the outer face of vthegeorrespondiiig side-"The frame 7 is. also provided with bores 3l passin through the yother side thereof adjacent the recesses l 22 and' 22a, which bores have`their'-outer'- ends 'counter-bored or enlarged to providev the lsockets or seats 32.

'. The 'egg-holder comprises a rectangular frame 10 having the inner. 'side v1l thereof beveled andfhaving a Wire filling 12 of polygf I onalmesh providing a plurality ofegg-re.-

ceiving openings '131 This filling v12'is ddsposed above the' bottom of the frame l0 and the openings 13 are elongated-1 and of such a sizeio permitV fhe eggsV to. passtheref.

, the dimen sionof the eggs.. i The frame 10 I with the opening 20,

i lroller 14a is arranged to be passed 'through f The respective bearings i j .19 are arranged 1n the recesses 22, 22, 22"l and 22% so that the said bearings ,are mount,-

'bis adapted to rest on the seat 9. within the vertical axes.

19,19, 19." and ed inthe frame 7 and within the inner faces thereof. The bearings 19 and 19 are provided with open slots 20 and 20", respectively, which register with the ways 21 and 21". The other bearings 19a and 19c are provided with the respective openings 20a andV 2O".A The bearings 19 and 19a are slidable longitudinally in the recesses 22 and 22", While the bearings 1-9b and 19c are snugly arranged within the recesses 22b and 22 and are immovable.'y

The rollers 14 and 14a are arranged within the frame 7 and have the respective pairs of trunnions 15---15a and 15b-15. The trunnion 15 of the roller 14 is adapted to enter the opening 20a of the bearing 19a and the other trunnion 15 of' the' said roller is adapted to pass through the Way 21 and enter the open slot 20 of the bearing 19, so that the trunnions of the roller 14 are jour# naled in the opposite bearings 19 and' 19". The trunnion 15c of the roller 14a is passed through the opening 20C, in the bearing 19 and through the bore 18- which registers the outer end of the trunnion 15E projecting into the socket or recess 17 and being squared for the engagement of a suitable key, as designated. by the numeral 16. The other trunnion 15" of the the way 211 to enter the open slot 20b of the bearing 19b so that the trunnions of the roller 14a are j ournaled in the opposite bearings 19b and 19C.

A belt or endless apron 33 is trained over or around the rollers 14 and 14, the upper run of the belt passing closely below the filling 12 of the eggsholder and being in the plane of the seat 9 and the bottom ofthe egg-holder.` The upper runA egg-holder 1s seated within the main frame 7, the eggs are raised or elevated slightly out of the openings 13 in order toI ermit the eggs to rotate freely when the elt is The openings 13 are elongated transversely of the belt 33`sothat the u Joper run of the belt may be shifted laterally of the said openings in order to rotate the eggs about horizontal axes.

Circular and elongated nuts 24 are journaled in the' bores 31 and have .the outer of the beltv forms a support for the eggs and when thev n iianges 25 engaging, in the sockets orseats 32. The bearings 19 and 19a are provided with threaded extensions 23'projecting there` from and engaging in the nuts 24 so that when the nuts are rotated, the bearings 19 and 19 may be adjusted or slid within the recesses 22 and 22a. The flanges 25 of the .nuts 24 are provided with outer notches or slots 26 for convenience in rotating the nut by meansof a screw-driver or other suitable implement. The 4flanges 25 engaging in the sockets'or seats 32 prevent the nuts from lbeing drawn inwardly, andwhen the'nuts are rotated in the proper direction, 14 may registration therewith to prevent the trununion 15 from being passed .upwardlythrough the way 21. In this manner, when theroller said roller will he locked against removal, and the open slots 20 and 20" are also inclined away from each other so that'when the belt is tightened, the trunnions 15 and 15" will be locked within the bearings 19 and 19b to prevent the removal of the rollers and the belt.

- Cleats 27 are attached tothe inner faces of the opposite sides'adjacent. the edges of the belt 33 and below-the seat 9, and a frame below the upper run of the belt-in order to support the upper run of thebelt against depression vwhen the eggs areseated thereon. This frame 28 comprises the longitudinal side bars 30 andi the crossvbars 29 connecting the longitudinal bars 28, the longitudinal bars 30 depending below the bars 29. The endmost cross birs 29 lare arranged to seat are adapted to engage the ends of the cleats 27 in orden to constrain the frame 28 against sliding movement on the cleats 27. When the belt 30 is removed, it will be seen that the frame 28 may be readily raised from the cleats 27 with the belt in order toremove the frame'28 lfrom the frame 7. It will therefore be apparent from the foregoin taken in" connection with the drawings, t at the belt 33 may be shifted by rotating the roller 14'L in order to shift the upper run of the belt 'transversely or laterally of the egg-re;- ceiving openings 13, this being accomp ished by means ofthe squared end` 16 of the trunnion 15 arranged within the socket or recess 17. Itnwill also be a-p arent, that by rotating the adjusted in order to tighten or loosen the belt,`and that when the belt is tightened, the rollers and the beltwill be locked against removal. By loosening the belt so as to bring the open slot 20 into the roller I be adjusted to tighten the belt. "When the bearings 19 and 1.9 are .adjusted l to tighten the belt, the o en slot 20 of the bearing 19 is moved out o registration with the way 21, or sutliciently out of complete y 28 is adapted to seat on the cleats 27 to pass 14 has been adjusted to tighten the belt, the
